ELECTRBC Application filed July 27K, T315.

Be it known that Gnomi citizen. of the limited Stains, iasiifliiig ll'csi: llart'liircl. county ofllartford, State of Conncr-ii'fiil. have invented a certain now and useful lmiiroveniimt iii Electric Sii'itches. of which the following is a full, doar, and exact dsciiplion.

My invention relates to electric switches and has for iisI object io produce a simple axial ifoiiiiiaol. ohio.. switch iii which a spring-prcwoil hall acts iiiioii a moiiiher Cai rying a cam lio iirodilci the desix'd snap liim'eiiimit. both iiicmliers oscillatiiii`y al'ioii a common axis.

Referring nim-o,parliniilarly to ihn ilrawings. l. is the switch hash of a two piish hiiton switch. on which is As'iiiiiiortml a pivot 2. @n ythis, pivot i is an icloiiggatod iiieiiilior 3 having in eaih and aii eloiigaliid chamber. vai-,h chamber coiiainiiig- :i hall 4 actod. iiiion hy a spring!
